I started redoing my flowerbeds a few months ago and got some of these lightweight landscape stones to stack as the border around the flowerbed. They were advertised as being able to be cut with woodworking tools and weighed a third or half as much as regular stones. I got them at Home Depot. They didn't have enough so I figured I would come back for the rest. Well, I've gone back repeatedly and to different stores and have gotten a few here and there but they were always sold out. Now it looks like they don't stock those anymore. Does anyone know what the brand name of those is so I can get the last ones I need?
